3M™ marine high strength repair filler restores damaged areas of fiberglass hulls, decks and other areas on boats. Our filler is a high performance product that is reinforced with short strands of fiberglass for added strength. Boat restoration professionals commonly use this product. 3M™ marine high strength repair filler is a uniquely modified vinyl ester structural filler formulated with short strand fiberglass for non-fairing applications. The fiberglass fibers interlock to give our filler additional strength compared to regular fillers. Filler is non-staining, non-shrinking and it comes with 3M™ marine creme hardener. We recommend this product for filling and covering scratches, dings, rust-outs, blemishes, pinholes and other simple surface defects that otherwise exhibit a true or fair line. Use this filler to level or even out depressions and low spots. 3M™ 7000120452, 2-Component 2-Part High Strength, 1 qt Container, Can Container, Part A: Viscous/Part B: Paste Form, Part A: Grayish Brown/Part B: Red, Part A: 740000 to 999999 cPs Viscosity, Chemical Composition: Part A: Inert Filler, Styrene Monomer, Vinyl Ester Resin, Wollastonite, Polyester Resin (Proprietary), Synthetic Crystalline Free Silica Gel, Polyester Polymer, Talc, Titanium Dioxide/Part B: Benzoyl Peroxide, Water, Benzoic Acid, C9-11-Branched Alkyl Esters, Zinc Stearate, Oxirane, Polymer with Methyloxirane, Monobutyl Ether, Calcium Sulfate, Iron Oxide (FE2O3), Ferric Ferrocyanide, Ferric Ammonium Ferrocyanide, 30 min Curing, Part A: 361 g/L VOC, Part A: Pungent Styrenic/Part B: Slight Ester Odor/Scent
